Keep geting called cheater because of my aim rating ( not real rating)?

In some games, people call me cheater because they see I have 98 aim rate on some sites.

The thing is, I dont have 98 aim rate, I dont think im bad, but im far way from that aim. I have gotten to lvl10 faceit, but then i lost rank.

My question is, where do they get the 98 rate when im clearly far from that?
